On the back of the book, you have A B C D E letters, the black spot on top of one of the letter is the revision.

All mag card labels are also GA1-xxA on my pac, so version A.

In the book, the following cards and listings are B version:
GA1-03B SLOT-MACHINE
GA1-05B ARTILLERY
GA1-13B RACETRACK
GA1-16B THE DEALER
